Lpi LPIC Exam 303: Security, version 3.0 Sample Questions (Q76-Q81):

NEW QUESTION # 76
What is the purpose of a Certificate Revocation List (CRL)?

Answer: B

Explanation:
A Certificate Revocation List (CRL) is a signed list published by a Certificate Authority that identifies certificates which have been revoked before their scheduled expiration date, for reasons such as key compromise or the certificate no longer being needed. Clients can download and check a CRL to determine whether a certificate they are relying on is still valid, though this approach has largely been supplemented or replaced in many contexts by the more efficient real- time OCSP protocol.


NEW QUESTION # 77
A LUKS device was mapped using the command: cryptsetup luksOpen/dev/sda1 crypt-vol Given that this device has three different keys, which of the following commands deletes only the first key?

Answer: A


NEW QUESTION # 78
What is the purpose of the pam_tally2 or pam_faillock module?

Answer: A

Explanation:
The pam_faillock module (and its older counterpart, pam_tally2) tracks the number of consecutive failed authentication attempts for a user account and can automatically lock the account after a configured threshold is reached, helping to mitigate brute-force password guessing attacks.
Administrators can configure the number of allowed attempts, the lockout duration, and whether the lockout applies even to the root account. This differs from password expiration, which is handled by fields in /etc/shadow and related PAM modules.


NEW QUESTION # 79
When OpenVPN sends a control packet to its peer, it expects an acknowledgement in 2 seconds by default. Which of the following options changes the timeout period to 5 seconds?
